For Lucius, his development could be a slow process. At first, he resents being around Hermione, but as he witnesses her magic and her kind heart, he starts to question his own values. He may begin to see the error of his ways regarding blood purity. Hermione might develop more patience. Dealing with Lucius, who has such different views, makes her learn to tolerate and try to change someone rather than just oppose them.
One possible plotline could be Lucius having a change of heart due to Hermione's intelligence and strong will. Maybe he starts to question his Death Eater beliefs as he interacts with her at Grimmauld Place. Another could be Hermione using her knowledge to outwit Lucius in some sort of magical duel or intellectual battle within the house.
One possibility is that they are there to retrieve some Dark Arts artifacts hidden in Grimmauld Place. Lucius believes that these artifacts can strengthen their position in Voldemort's ranks. Draco, on the other hand, is starting to question the morality of using such artifacts. As they search, they come across old memories and secrets of the Black family that make Draco wonder if the path his family has chosen is the right one. He might start to see the value in the Order of the Phoenix's fight against the Dark Arts, even if he doesn't fully support them yet.
A scenario could be that Lucius has received a tip that there are valuable Dark objects at Grimmauld Place. So, he takes Draco with him. When they arrive, they are met with the powerful protective enchantments. Lucius tries to break through them, but Draco is hesitant, seeing the strength of the magic. He starts to think that maybe the Order of the Phoenix is not as weak as his father always said.
In this fanfiction setting, Snape might be at Grimmauld Place on some secret mission. Hermione, being the inquisitive witch she is, could stumble upon him.

This shared purpose could make Snape view Hermione as an equal, rather than a student, and Hermione could see Snape's true loyalty and sacrifice, thus changing their relationship for the better.
